The population of Côte d'Ivoire in 2003 was estimated by the United Nations at 16,631,000, which placed it as number 57 in population among the 193 nations of the world. In that year approximately 2% of the population was over 65 years of age, with another 47% of the population under 15 years of age. There were 104 males for every 100 females in the country in 2003. According to the UN, the annual population growth rate for 2000–2005 is 1.62%, with the projected population for the year 2015 at 19,837,000. The population density in 2002 was 52 per sq km (135 per sq mi).
Movement to the cities has been a problem in recent decades. The proportion of urban dwellers has increased from 13.2% in 1950 to an estimated 46% of the population in 2001 according to the Population Reference Bureau. The capital city, Yamoussoukro, had a population of 3,199,000 in that year. The metropolitan population of Abidjan, the former capital, was estimated at 2,793,000. Other major urban areas are Bouaké (estimated at more than 390,000), the capital city of Yamoussoukro (120,000), and Daloa (102,000); other towns with populations of more than 20,000 include Gagnoa, Korhogo, Agboville, Abengourou, Dimbokro, Man, and Grand Bassam. According to the United Nations, the urban population growth rate for the period 2000–2005 was 3.4%.
The prevalence of AIDS/HIV has had a significant impact on the population of Côte d'Ivoire. The United Nations estimated that 9.6% of adults between the ages of 15–49 were living with HIV/AIDS in 2001. The AIDS epidemic causes higher death and infant mortality rates, and lowers life expectancy.
